Benefits of technology

[0011]In view of the prior art as described above, the object of the present invention is to provide a scrap tire recycling plant ensuring an excellent yield per time unit in terms of recovered material, i.e., rubber, metal and textile material, as well as a high purity of the recovered material.

Problems solved by technology

Tires are known to have a limited life and have to be replaced when they become useless.
Some of the mechanical scrap tire recycling plants known in the art, e.g., from RO118939, can recover a more or less substantial portion of the rubber, but do not address the problem of recovering the other components.
Nonetheless, the plant disclosed therein does not ensure a high yield (in terms of rubber recovered per time unit) and is not able to perfectly clean the metal cording; due to their poor purity, the products recovered thereby are rather difficultly marketable.

Embodiment Construction

[0019]Referring to FIG. 1, the plant may comprise a plurality of workstations: the first station 1 may be an “intelligent” station in which scrap tires 100 are pre-selected and loaded into the second station 2, which may be a scrap tire 100 disgregating station, possibly having a device, e.g., a Water Jet device, for disgregating the rubber and fabric of the tread 101 and / or the shoulder 102 and / or means for separating the residual metal material.

[0020]The rubber and fabric disgregated into crumbs and fibers by the second station 2 may be collected with the Water Jet pump liquids in a third station 3 which provides, possibly at a later time, a (rubber or fiber) powder having a very low moisture content.

[0021]A fourth station 4 separates the rubber crumbs from the textile particles while further drying the product and conveys the rubber crumbs to a fifth screening station 5, in which the crumbs are separated according to their size.

[0022]A plant of this type provides an unprecedented...

Abstract

The present invention relates to a device, a plant and a method for disgregating scrap tires, which provide recycled material (rubber crumbs, metal, textile product) having a very high degree of purity. The device, plant and method of the present invention further provide a high yield of material per time unit. In practice, the present invention concerns disgregation of scrap tire shoulders.

Description

TECHNICAL FIELD[0001]The present invention relates to a scrap tire recycling plant.BACKGROUND OF THE INVENTION[0002]Modern society is mainly based on road transport: cars, motorcycles, tractors and trucks are some of means of transport that manifestly use tires every day.[0003]Tires are known to have a limited life and have to be replaced when they become useless. Unusable tires, such as excessively worn or damaged tires, are known as scrap tires.[0004]Scrap tires are a contaminating product, one tire, e.g., a car tire, taking about 100 years to full disposal.[0005]Considering that scrap tires can be counted in hundreds of millions in the industrialized world, it is clear that they create a major environmental concern.[0006]Any scrap tire recycling attempt performed so far has addressed the problem of separating scrap tires into their main components: textiles, metals (typically steel) and rubber.[0007]Some of the mechanical scrap tire recycling plants known in the art, e.g., from R...
